To find the drip rate in gtt/min, which mathematical operations must be performed?

To determine the drip rate in gtt/min (drops per minute), one must calculate the total volume of the solution to be infused and the duration of the infusion in minutes. The calculation typically involves dividing the total volume by the infusion time, which gives the flow rate in volume per minute. Then, this volume must be converted into drops by applying a factor that corresponds to the drop factor of the intravenous equipment being used. This drop factor is a constant that represents how many drops are contained in a certain volume (for example, milliliters).

Thus, the correct mathematical operations include multiplication (when calculating total drops based on volume) and division (when determining volume per time). The answer reflects this blend of operations necessary for deriving the drip rate accurately, incorporating both the division of volume by time and multiplication for converting volume to drops based on the drop factor.
